The approach combines the relatively new field of forensic genetic genealogy—solving crime by charting out DNA-based family trees—with increasing computational power to speed up and simplify ...
DNA information from crimes is collected and deposited into the CODIS database, which is maintained by the FBI. CODIS enables law enforcement officials to test DNA samples from crimes for matches within the database, providing a means of finding specific biological profiles associated with collected DNA evidence.

Based on data from 4,700 mass murderers, 57% of serial killers are white whereas only 29% are African American. [27] It has been suggested that the use of investigative genetic genealogy, which relies heavily on databases like GEDMatch, would therefore help to reduce racial disparities in the current criminal justice system.
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

STRmix’s technology promises to help solve what has long been an issue in DNA analysis: The tinier the sample and the more complex it is — if it contained genetic material from multiple people ...
Forty million people have done these DNA tests in the U.S. People don’t think about the fact that you might be contributing to the discovery of a criminal in your own family, even if it’s ...
CHICAGO (CBS) -- Investigators in Wisconsin have used DNA evidence to solve a 65-year-old cold case involving a 7-year-old boy whose body was found in a culvert.
Touch DNA, also known as Trace DNA, is a forensic method for analyzing DNA left at the scene of a crime. It is called "touch DNA" because it only requires very small samples, for example from the skin cells left on an object after it has been touched or casually handled, [ 1 ] or from footprints. [ 2 ]
